Multi-component seismic exploration may give more information.

This article applies the theory and method of engineering multi-wave seismic exploration and uses the DC_4 high-frequency multi-wave detector and single heft、3-heft energy exchangeer to do multi-wave observation experiments on the scared train-axle model.

According to the theory of the multi-wave seismis exploration, and due to the fact that the ultrasonic multi-wave metal detector cannot locate a crack and detect its, size and shape, this article studies the principle and characteristics of the ultrasonic multi-wave metal detector and also the 3-heft energy-exchange instrument in match with the ultrasonic multi-wave metal detector.

VSP multiwave image with Kirchhoff Method;

At the present phase during which to discover the dense fracture belt of a targetformation is considered as the most important task, fracture density determinationusing multiwave information becomes the matter people pay closest attention to.

Based on the 3?layers medium model, we have analyzed the multiwave AVO effects for the medium models.

Data fusion is one of the attractive topics in multi wave data processing.

Because P wave is related to Lame coefficients λ and μ, S wave is related just to μ, multi wave exploration is favorable for solving the above mentioned problems.
